|ACS 2006-1yr Summary File: Technical Documentation -> Appendix B. Subject Definitions -> Derived Measures -> Mean -> Aggregate|
An aggregate is the sum of the values for each of the elements in the universe. For example, aggregate household income is the sum of the incomes of all households in a given geographic area. Means are derived by dividing the aggregate by the appropriate universe. When an aggregate used as a numerator is rounded in the detailed (base) tables, the rounded value is used for the calculation of the mean.
